I v I VEHICLE-TIRE RIM-Y I To all whom it may concern:

Be it known that I, ARTHUR L. BANKER, a citizen of the United States ,residing at Pittsburg, in the State of Pennsylvania, have invented certain new and useful Improvements retaining ring is reversible to accommodate "either the beaded clencher tire or the ordinary y the accompanying drawings, in which Figure 1 IS a sine View of a wheel provided fiangeless tire.

p the rim at the. point at which the retaining-- fiangeless tire; to provide an effectual and simple locking means forthe ends of the re-' taining rings, whereby radial movement of such ends is prevented, and to provide a construction in which the retaining rim maybe locked positively and securely to the base rim and held from movement in all directions.

The preferred form of the device is shown in with applicants rim and equipped with a tire. Figure 2 is a transverse section thror gh the rim showing the reversible retaining rings applied to abeaded tire.

Figtre 3 is a similar section showing the retaining-rings as applied to the ordinary Figure 4 is a longitudinal section through ring ends are scctred, and showing the means whereby 1 the ends are locked together. Figure 5 is a detail showing the collar for SGGL. ring the ends of the retaining ring.

ifiigtre-ti is a transverse section through a modified form of retaining collar in whicha cam locking means is used instead of the tires in the usual way,and consists of the base rim to which the spokes are attached and two oppositely disposed detachable retaining rings for engaging the edge of the tire. These ring are'made reversible so that they may accommodateeither the beaded them the flangeless tire, and are split so that they may be easily placed about the wheel, and are provided at their meeting ends with looking devices wherebythe rings ma be securely clamped about the wheel. he locking .means is also adjustable whereby if the ring does not fit'exactly and the ends do not come Specification of Letters Patent.

commodate itself to the inaccuracy. The

I exactly together the locking means may acrings are also provided with means for engaging the base rim to prevent circumferential or creeping movement thereon.

As shown in Figure 1, 7 is the wheel body of any preferred type, 8 is the base rim and 9 is the tire. The cross section of the base rim 8 is clearly shown in Figures 2 and 3, audit will be noted that such rim has a flat face and is provided at its side with upstanding beads 10 adapted to engage the sides of the rings 11 i and 12. These retaining rings are concave on one side to fit a'clencher tire as indicated in FigureZ, and convex on the other sideto fit the ordinary flangeless tire as shown in Figure 3. These rings are separable as shown I in Figure 4, and the ends thereof are securedtogether by a locking means, thereby clamping the ring about the base rim. The locking means which is the same for both rings, is

adapted to project through the slot 13 in the i base rim, and is provided with a collar 14 for holding such ends. The collar 14 is large enorgh to slip over the lugs 15, and has a screw 16 for clamping'the collar in enga ement over the interlocking ends. In or er to'prevent lateral movement, of the twoends relative to each other in a direction radial t0 thewheel, a recess 17 is provided on one end and an interfitting lug 18 on the other end, and in order to hold the one end securely during the application of the ring on the rim, a 112g 19 is provided on one of the ends for fitting under the base rim 8. The pins 20 in the retaining rings fittingdetachably into recesses in the base rim are provided to prevent circumferential or creeping movement thereof and to hold the retaining ring in place and prevent it from pushing backward and obstructing the slot 13 when the other end of the ring is being applied to the base rim. The slots 13 for the opposing retaining rings are placed at 180 from each other in order that the base rim may not'be unduly weakened at if the slots'for the rings 11 and 12 were adjacent.

In Figure 6 a modified locliing means for the collar is shown. This locking means con= sists. of the cam 21.ha.ving a handle 22: As shown in Figure 6, the cam is in locking position, in which position thepoint of the cam is nearest the opposite side of the The cam is held in closedpos ition by the bolt 23 any one point, as would of-cou'rse be the case other retaining ring. The object attained in this construction is the lowering of the head 26 so that the tire can be easily slipped on and of on that side;

The operation in removing the ring is as follows: The screw 16 is loosened sufficiently to allow the collar 14 to' slip over the head 15; the right hand end of the ring as shown in Figure 4 is then sprung to the right so that it can slip out through the slot 13, and the entire ring is then expanded to, free the circumferential holding pins 20, after which the left hand end of the ring as shown in Figure 4 may be slipped to the right, thereby freeing the lug 19 from the rim. The operation of replacing the rim will be the reverse of that just described, .and a description thereof is unnecessary.

The advantage of my construction will be apparent to those skilled in the art. It is obvious that the rim may be very easily and conveniently displaced and put back again;

and that the rim when in place is braced and secured in every possible direction, the head 10 preventing sidewise movement of the rim, the lug 18 reventing relative movement of the ends 0 the ring in a direction radial to the wheel, the lug 19 preventing a relative movement of the base rim and the retaining ring in a direction radial to the wheel, and

I the pins 20 preventing circumferential or creeping movement of the ring and holding the lug 19 in place. It will also be noted that by making the base rim flat a superior bearing surface for the flat faced retaining ring is provided. Another important advantage resides in the adjustability of the collar and screw holding means as such adj-ustability provides a means for compensatmg for any inaccuracy of fit of the retaining rings over the base rim. In other words the retaining ring if not exactlg the right length may within certain limits e made to fit by adjusting the screw 16, thereby bringing the ring ends closer or further apart as desired. This feature has considerable bearing on the cost of production as it obviates the necessity of great accuracy of construction which heretofore has been imperative in this class ,of detachable rims.

It will be apparent that various modifications might be made from the referred form of structure shown, without eparting from the invention, as for insianw, the provision of a different style of loililllg means in place of the parts 17 and 13, the use ol some other engaging means for the under side of the rim other than a projecting lug 1), or'thc use of some other securing means than the collar 14, as for instance a bolt or turnbuckle cxtending through thotwo ends. All of these modifications are within the scope of my invention, and are covered by the claims.

Having thus described my invention and illustrated its use, what 1 claim as n'cn', and desire to secure by Letters Patent, is the following:

1. In combination, a beaded flat base rim, 8. pair of reversible separable retaining rings having flat seats on the base rim and adapted to engage on opposite sides when. in one position a beaded tire and when in another position a flangeless tire, means to fasterrthe ends of the rings, and other interlocking meansadapted to prevent movement of the ends relative to each other in a direction radial to the wheel.
